How to groom arm hair? Specifically inner forearm hair

Grooming arm hair, advice please!

I am very hairy. I have hair on my arms, everywhere. From my armpits, it grows down my inner bicep, from my shoulders it grows down my outer bicep. I have very hairy forearms, even very dense but wispy hair on the inside of my forearms.

I can’t find a guide anywhere that shows how to remove the hair on my upper arms, and specifically my inner forearms whilst leaving the outer forearm area intact (where hair should be!)

Id appreciate some advice, perhaps a diagram to show where to remove hair and where to leave it on my arm because I’m very self conscious of the inner forearm hair particularly as I think it looks unsightly and would like to not have it.
